western rock jasmine

Western rock jasmine (Androsace occidentalis) is a small annual forb that occurs in North America between the Rocky Mountains and the Mississippi River. In Minnesota it is occasional in the western, southern, and central regions, absent from the northeast. It may be the smallest terrestrial wildflower native to Minnesota. It is usually no more than 3″ tall. It appears as a 1½″ in diameter radiating cluster of leaves and up to 15 leafless flower stalks. The flowers are white and about 1 ⁄16″ wide.

Western rock jasmine is short-lived, flowering from April to May and dying back by mid-summer. It is easily overlooked due to its diminutive size. For these reasons it may be more common than reported.
